From 4ad933304cb75986ba9e50f5618b9d8abf536079 Mon Sep 17 00:00:00 2001 From: Seung-Woo Kim Date: Mon, 19 Mar 2018 11:20:12 +0900 Subject: [PATCH] rpi3: config: add config.txt for 32bit Add config.txt for 32bit. Note: It is for rpi3 32bit and rpi2, and in 32bit, there is no atf implementation, so booting is done with u-boot.bin instead of u-boot-spl.bin.
